,The invention relates to 2 Claims.

a stock car as described in the present specication and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially of the novel features of construction pointed out broadly and specically in containing an explanation able form of the invention.

depending on weather conditions and the type of stock being carried, to furnish operating gear which r`will be protected from the weather and from damage and which can be operated from many different locations inside and outside; to furnish a car which can readily be converted for carrying different types of stock while retaining the necessary ventilation,

and generally to provide a stock car which will give the greatest protection and comfort and at the same time provide efficient and economical tr ansportation.

similar to Figure 4 on the line position.

Like numerals oi referen ce indicate corresponding parts in the Various gures.

The frame of the car co supported on the side rails nsisting of the floor I5 I6 and the end walls (Cl. 11S-8) is according to modern construction of stock cars, and supports the roof I8 through the top rail members I9.

Intermediate vertical brace members 20 and 2l support the frame throughout its length, while doors 22 provide an entrance to the car on each side at the center.

A series of longitudinal slats 23 spaced above the base board 24 provide Ventilating spaces 25, while at the top broad Slat 26 is spaced down from the top of the car to provide the permanent ventilator opening 21.

lThis represents standard construction of cars of this type and it is from now on that I proceed to describe the particular features of my inven- 1 tion.

Shutter forms comprising longitudinal slats 28 are mounted on the vertical standards 29 and are made in two sections 30 and 3|, which can be joined together or separated by means of the attachment 32 which is here shown in the form of a bolt joining the abutting ends of the Vertical standards 29.

A block 33 and box board 34 provide a recess and guide for the lower section 30, while the ends of the sections are held in place by the guide bars 35.

The bull bar 3B which is rigidly mounted between the door post 31 and the end wall of the car provides a guide for the upper section 3l which also slides behind the guide bars 35.

The spacing of the slats 29 on the lower section 3G is arranged to cover the lower slots 25 except the one immediately below the bull bar 36, this particular slot and the ones between the bull bar and the slot 26 are shut oi when the upper section 3I of the shutter is lowered.

Operating mechanism for controlling the shutter forms is provided, operable from both inside and outside the car, and consists of chain and pulley gear at the ends of the forms. The pulleys 3B are mounted on brackets on the door post at one end, while the pulleys 39 are mounted on brackets on the top rail I9 in vertical alignment with the iower pulleys 3a. 45

A chain 4E) is led over these pulleys 38 and 39 and has its ends secured to the top of the vertical standard 29 of the upper section 3l.

A bar 4I extends the full length of the car and is rotatably mounted in the end bearing brackets 42 and can be suitably supported throughout its length. Levers 43 are keyed to the bar 4I and are secured at their other ends to the chains 40 in any suitable manner, and extend into operating hand levers 44. 55

In the length of the car there are therefore four sets of operating mechanism, one on either side of the door and one at each end of the car, and this arrangement is duplicated in the opposite side of the car.

The inside operating mechanism consists of a crank lever 45 rigidly secured on the bar 4| adjacent the door of the car and connects with a rod 46 extending downwards through an opening in the oor I5 of the car, to connect with the crank lever 41 mounted on the end of the stub shaft 48 journalled in the side rail I6. A hand lever 49 is mounted on the stub shaft 48 outside the side rail.

I6. This inside operating mechanism is also duplicated on. the othe1` side of the car, and being centrally placed with respect to the length of the car ensures efcient operation of the shutter forms.

Suitable latches or hooks 53 are provided on the car frame to hold the lever 49 in its set position, and similar latches or hooks 5| hold the levers 44.

In the operation of this invention the upper and lower sections of the shutter form are connected or disconnected depending on the amount of ventilation required, so that all of the ventilatory slots 25 can be closed or opened at one time when the two sections are connected, or when the sections are disconnected, the lower section 3|) rests on top of the block 33 and the slats 28 close the lower three openings 25, as shown in Figure 4 of the drawings, while the upper section 3| can be raised or lowered by the operating mechanism to close or open the remaining slots 25.

The chain and lever operating mechanism is positive in its action and is thoroughly protected from the effects of weather, while it is quite out of the way of the cattle, and is more or less out of reach against casual or accidental movement of the levers.

The outside operating mechanism is direct, with no loose parts to wear out or become affected by the weather.

With this device it is possible to have ample ventilation, as should the lower section become frozen in or 'be clogged by dirt, it is always possible to open the upper slots as they are above' the point `of being aiected by weather or dirt, and together with the slot 2'| which is always open, give a large degree of ventilation.

Where cars are equipped with a platform for carrying hogs or such smaller animals, there can always be ventilation of the rst level as the platform is set in at the level of the bull bar and the 'slot `immediately below is controlled by the upper section 3| of theshutter.

Where deemed necessary the operating mecha nism can be encased for further protection andwhile a chain and pulley method of operating the shutter sections is shown the applicants do not limit themselves lof this particular construetion and Wires or rods may be substituted.

What we claim is 1. lIn a stock car, a box frame mounted on a. suitable running gear and having slotted sides and entrances and exits, a bull bar at approximately Amidway Lof the height of the car and forming va -base for a platform, an upper slotted frame mounted in ways and adapted to cover the slots of the side above and immediately below the said bull bar, and a llower slotted frame set in the way below said upper frame and adapted -to be connected thereto, and operating means connected to the Vupper 4frame and adapted to slide the same independent `of the lower frame.

2. In a stock car, a box frame mounted on a suitable running gear and having slotted sides `and entrances and exits, guideways mountedon said -box frame, upper and lower slotted frames sliding `in said guideways 4and forming temporary-closures, an operating mechanism compris ing vertically spaced pulleys, endless chains vtrained on said pulleys and xedly rconnected to the upper slotted frame, a lbar lextending the length of the car and rotatively mounted and cranks mounted on said bar opposite each of said chains and permanently secured thereto on oneside, and means to yconnect the lower frame to the upper frame.
